The Science Behind Keto Macros

1. Why Macros Matter More Than Calories

• Keto isn’t just about low carbs—it’s about ratios.
• The standard keto macro split: 70-80% fat, 15-25% protein, 5-10% carbs.
• Too much protein? Your body might convert it to glucose (kicking you out of ketosis).

2. How Ketosis Works

• When carbs are restricted (<50g/day), your body burns fat for fuel instead.
• This produces ketones, an efficient energy source for your brain and muscles.

3. The Role of Each Macronutrient

• Fats – Keep you full and fuel ketosis (avocados, olive oil, nuts).
• Protein – Maintains muscle (chicken, fish, eggs).
• Carbs – Only from fibrous veggies (spinach, broccoli, zucchini).

5 Tips to Hit Your Macros Consistently

1. Track Your Food (At Least at First)

• Apps like Cronometer or MyFitnessPal help you stay on target.
• After a few weeks, you’ll naturally eyeball portions.

2. Meal Prep Like a Pro

• Cook batches of fatty meats, roasted veggies, and keto sauces.
• Example meal: Salmon + avocado + sautéed spinach.

3. Don’t Fear Healthy Fats

• Many new keto dieters undereat fat, leaving them hungry.
• Add butter, coconut oil, or MCT oil to meals.

4. Stay Hydrated & Mind Electrolytes

• Keto flushes water weight, so you lose electrolytes.
• Drink bone broth or add salt + potassium to water.

5. Adjust as Needed

• If weight loss stalls, recalculate your macros (metabolism adapts!).

Common Keto Mistakes (And How to Avoid Them)

❌ Eating Too Many “Keto” Processed Foods

• Keto cookies and bars often contain hidden carbs.
• Fix: Stick to whole foods 90% of the time.

❌ Neglecting Fiber

• Low-carb veggies prevent constipation and feed gut bacteria.
• Fix: Eat 2-3 cups of leafy greens daily.

❌ Not Checking for Hidden Carbs

• Sauces, dressings, and nuts can add up quickly.
• Fix: Read labels and track everything at first.

FAQs About Keto Macros

Q: Can I eat unlimited fat on keto?

No! While fat is a primary energy source, excess calories still lead to weight gain.

Q: What if I go over my carb limit?

Don’t panic—just get back on track the next meal. Consistency matters more than perfection.

Q: How often should I recalculate my macros?

Every 10-15 lbs lost or if your activity level changes significantly.
